Hi from Russia guys! Recently I had a sound like on video. Tell me please, is this a normal sound in 350z?

THANKS!!!

 

The sound disappears when I squeeze the clutch. When the clutch is released, the sound appears.

 

Sounds like a worn throwout bearing.

 

Throwout bearing for sure... How many mile on the clutch assembly?

 

After removing the gearbox, all the bearings in the box were replaced. After that, I bought a new clutch kit, including the release bearing. After installation, the sound still remained, but it became quieter. What's wrong with my box?

 

75,000 miles mileage

 

Regards, Imbalan: When the clutch pedal is pushed to the floor the throwout bearing is under tension. If the bearing is faulty it is at this position you will hear a raspy or (worse) shrill sound. When lifting the clutch pedal the pressure on the throwout bearing is relieved. Even if defective it should be quiet.

The most common noise with the Z's drivetrain is due to play in the bearings carrying the transmission's front (line) shaft, a rattling noise usually described as a "cement mixer" or "coffee can full of marbles".

If this is what you are hearing, pay attention but this is typically more an annoyance than a sign of imminent failure.

 

At 75k your clutch assembly and throw-out bearing should be OK. The problem you describe might be with the bearings. See this post:
